Member Function Documentation

readTObject()

TObject * readTObject ( )

inline

Read one object from the message assuming it inherits from TObject.

Definition at line 99 of file MsgHandler.h.

{ return static_cast<TObject*>(ReadObjectAny(TObject::Class())); }

SetBuffer()

void SetBuffer ( const void *  ptr, UInt_t  bufsize  )

inline

Replace buffer (doesn't take ownership).

Definition at line 85 of file MsgHandler.h.

    {
      TBuffer::SetBuffer(const_cast<void*>(ptr), bufsize, false);
      // TMessage has an extra header of two ints: a reserved size field and a
      // fWhat pointer indicating the type of the message.  We force the message
      // to be MESS_OBJECT so we don't care. Let's put the buffer where we need
      // it to be. The original constructor has a ReadClass() here but we skip
      // it since we read everything as TObject.
      SetBufferOffset(sizeof(UInt_t) * 2);
      // and reset the map of objects/classes seen so far
      ResetMap();
    }
